Welcome to Gaia! ::

I don`t think you`re crazy. I could write to you a long story about that issue, but I think that would burst that forum. So just be assured you`re not crazy, take a good look at what you paint and observe the environment when you paint them. Do you feel a chill in the room although it was warm before? A positive or negative presence around you?

In anything you do make sure that you are in control of the situation, that you can stop when you want to. Noone and nothing has the right to control you, use you or own you without your consent.
On a personal note, but that`s just me: a prayer or positive thought can help when under attack.
